Windows 10 can't connect to network resources over VPN

Hello all, this is my first post I've been avoiding it, but I need some help.

My company runs their VPN through a Sonicwall nsa220. Some time in June, our Windows 10 laptops could no longer connect to our companies resources over the VPN. I emphasize Windows 10, because all our Windows 7 Laptops and PCs can still connect without issues. If I logon to the Sonicwall, I can see the PC and the user logged in, so they do successfully logon.

I don't want to list it all off everything I've tried, if it shows up on the first 2 pages of a cursory googling, I'm pretty sure I've tried it.

I know Microsoft had the update issue around this time, but it would seem odd that it wouldn't be fixed by now. Please let me know what you think.
Really quick to save us all time, I've tried the UDP Encapsulation registry trick, DNS flush, change subnets, change...
